The Appreciative Inquiry Change Agents (CA) program (NAMWEZA) intends to address broad societal issues by engaging HIV-positive leaders as 'change agents' in their communities. In this study, the CAs will be recruited from an HIV Care and Treatment Centre in Dar es Salaam. The Namweza program has the potential to address structural issues related to HIV risk, such as access to limited resources, through an entrepreneurial component of the program. A positive, or appreciative, focus promotes CAs to examine assets in themselves and in their networks, encourages strengthening of relationships, and facilitates planning for a positive future for themselves, their families, and their communities.
A stepped wedge randomized trial will be performed to evaluate the effectiveness of the program for the following primary outcomes: uptake of HIV services among network members of the CAs; rate of unprotected sex and frequency of concurrent relationships among CAs and their social networks; and levels of self-esteem, general self efficacy, and risk of intimate partner violence in the CAs. Secondary outcomes include: depressive symptoms, hopefulness, and HIV-related stigma (among CAs); social support and quality of relationships (among CAs); and HIV knowledge, attitudes and self-efficacy in preventing HIV transmission or re-infection (CAs and their networks).
The following are primary hypotheses that will be tested through this stepped wedge randomized trial evaluation:
- Uptake of HIV services will increase among individuals in the network of the HIV-positive Change Agents related to the intervention;
- Levels of self-esteem and general self-efficacy will increase in trained Change Agents;
- Rate of unprotected sex and number of concurrent partners will decrease (among network of Change Agents as well as Change Agents themselves; i.e. the 'study population'); and
-
Prevalence of intimate partner violence (IPV) will decrease in Change Agents.
Secondary hypotheses are:
- Prevalence of depressive symptoms and HIV-related stigma will decrease and level of hopefulness will increase in trained Change Agents;
- Levels of HIV knowledge, attitudes and self-efficacy in preventing HIV transmission and re-infection among CA and their networks will increase; and
- Degree of social support and quality of relationships will improve among CA.
If the proposed intervention is found to be effective, linkages with the Tanzanian Ministry of Health and other stakeholders will enable scale-up of the program throughout the country.

Behavioral: Appreciative Inquiry Change Agents (CA) program (NAMWEZA)
The intervention is based on an Appreciative Inquiry approach that comprises a 10-session program based on learning by doing rather than factual classroom type learning, although it includes discussion of relevant facts about HIV, and other STIs. The intervention is based on the template of Stepping Stones (Jewkes et al., 2008), which is internationally one of the most widely used participatory behavioral interventions targeting sexual health. The Stepping Stones curriculum was shortened and radically adapted from more than 20 sessions. However NAMWEZA borrows generously from many of the exercises and games. It also employs the successful experience of stratification by age and sex to engage 4 different working groups (younger and older, male and female).

Placebo Comparator: Control group
Since the design is a stepped-wedge randomized trial, those in the control group will eventually receive the intervention later in the study.
